Renesas公司的RAJ306001和RAJ306010是用于三相无刷DC马达应用的通用马达控制集成电路,在同一封装内组合了MCU(RL78/G1F)和预驱动器. 预驱动器包括半桥栅极驱动器,5V稳压器,电流检测放大器,霍尔IC比较器, Back-EMF放大器和各种保护功能(超温,过压/欠压,过流和马达锁住检测).三个半桥栅极驱动器提供高效率和高度灵活调整栅极驱动峰值电流(500mA),自对准死区发生器,可选择栅极驱动电压和控制信号配置功能.MCU支持安全标准IEC60730的硬件,也可提供RL78系列开发工具. RAJ306001的工作电压为6V到30V,
RAJ306010工作电压为6V 到 42V,而RAJ3060xxGNP工作温度-40 到 +85C, RAJ3060xxZGNP工作温度为-40 到 +105C.主要用在电动工具,花园工具和真空清洁器以及打印机,风扇,泵和机器人.本文介绍了RAJ306001和RAJ306010主要特性,框图和推荐外部电路图,评估板RAJ306010 RSSK主要特性和主要指标,功能框图和框图,材料清单和PCB设计图.
RAJ306001 and RAJ306010 are general-purpose motor control ICs for three phase Brushless DC motor applications. RAJ306001 and RAJ306010 combine MCU(RL78/G1F) and a pre-driver in a single package. The pre-driver includes half bridge gate drivers, 5V regulator, a current sense amplifier, hall IC comparators, Back-EMF amplifier, and various protection functions (overtemperature, over/under voltage, overcurrent and the motor lock detection).
